Application July 25, 1945, Serial No. 606,985

This invention relates to a window sash mounting and operating mechanism.

An object of the invention is to provide novel means for mounting a window sash whereby the sash may be conveniently opened and closed.

Another object of the invention is to provide means for mounting a window sash, or similar closure, whereby the sash, or closure, may be moved to open position to allow adequate circulation of air but to exclude the rain.

It is a further object of the invention to provide a window sash mounting of the character described whereby the sash, when moved to closed position will form an effective seal with the window casing so as to exclude rain and moisture.

It is another object of the invention to provide a sash mounting that may be easily operated.

A still further object of the invention is to provide in combination with said sash and mounting a window blind by means of which the admission of light and air may be controlled.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein:

Figure 1 is a vertical, sectional view taken on the line |-l of Figure 3 showing the sash in closed position.

Figure 2 is a similar view showing the sash open.

Figure 3 is a vertical, sectional view taken on the line 33 of Figure 4.

Figure 4 is a vertical, sectional view taken on the line 4--4 of Figure 3.

Figure 5 is a fragmentary, horizontal, sectional view taken on the line 5--5 of Figure 3.

Figure 6 is a fragmentary, horizontal, sectional view of the window blind employed; and

Figure 7 is a vertical, sectional view thereof taken on the line l-! of Figure 6.

Referring now more particularly to the drawings wherein like numerals of reference desi nate similar parts in each of the figures, the numeral I designates the Window casing which, in general construction, is of conventional form. It may be composed of wood or of sheet metal, the latter construction being shown in Figure 5. At the top and bottom of the window casing there are the transverse outwardly and downwardly tapering seats 2 and 3.

The numeral 4 designates the sash, as a whole, which may be of any conventional construction 8 Claims. (Cl. 268108) but whose upper and lowerendsare downwardly and outwardly tapered so as to fit closely against .the. tapering seats 2 and 3 when the sash is closed, as shown in Figures 1 and 4.

mechanism mounting the sash is located.

The numeral 1 designates a transverse shaft which is mounted to rotate in suitable hearings in the casing and which is located at the top of the casing.

Fixed on this shaft in the respective spaces ii and 6 are the crossheads 8, 8. The upperends of the links 9, 9 are pivoted to the corresponding ends of said crossheads and the lower ends of these links are pivoted to the lift levers HI, l0 which are located in the spaces 5 and 6 at the lower ends thereof. The outer ends of these lifting levers are pivoted to the window casing, as

shown in Figures 1 and 2, and their inner ends Fastened on the sides of the sash frame are the brackets l5 and these brackets are connected to the lower apexes of the swinging plates l3 by means of the links I6, 18.

Fixed to the shaft I in the space 6 of th casing there is an arm I! and pivotally connected, at its upper end, to the free end of this arm, there is a link 18. The lower end of this link is pivoted to the free end of one of the arms of the bell-crank l9 and the free end of the other arm of said bell-crank is pivoted to one end of the link 20. The other end of this link 20 is pivoted to a nut 2| which is threaded onto the outwardly threaded shaft 2 2. This shaft is mounted to rotate in outer and inner bearings in a casing 23 which is located in the space 6 and which is fastened to the adjacent side of the I9 is also window casing. The bell-crank mounted in this casing 23 and the link 20 and nutZl are enclosed by it.

The inner end of the shaft 22 extends into a bore 24 in the side of the casingv l and is poly onal in shape to receivea socketwrench 25 by 3 means of which the shaft 22 may be turned so as to move the nut 2| along said shaft.

As the shaft 22 is turned to move the nut 2| inwardly the bell-crank 19 will be actuated to cause a downward pull on the link I8 which, in turn, will pull the arm I! downwardly and correspondingly rotate the shaft 1. The rotation of the shaft 1' will revolve the crossheads 8 with a lifting effector; thefl'li'nks' 9, 3 so that the levers ID will be'moved upwardly. At the same time the links M and the swinging plates l3 will be actuated to move the lower apexes of said swinging plates upwardly and inwardly. The sash 4 will thus be lifted and its lower end will be moved slightly outwardly on account of the connection of the outer ends of the levers It! withthe brackets II but by reason of the. connection of the links it with the brackets [5 the upper end of the sash will be moved further inwardly than the lower end thereof thus allowing circulation beneath and above the sash as well, as aboutthe. sides thereof. 7

The sash mountingmechanism in the spaces 5- and 6 operate in unison being simultaneously operated by the common shaft 1.

Upon rotation of the shaft 22 in the other direction the nut 21- will be moved outwardly and the-movement of the sash will be reversed and the sash, will bemovecl outwardly and downwardly and its upper and lower ends will be seated,

against the corresponding seats, or faces, 2" and 3 and the window opening thus tightly closed by the sash. I

Mounted in the window casing l outside of the sash 4 there isa Venetian blind comprising the spaced, vertical side bars 26, 25 preferably angleirons and the spaced cross slats 2?. The ends 28 of these cross slats are overturned at right angles to the slats and have the end extensions which are pivoted to the bars 26. The overturned ends 28 of the upper and lower cross slats each have the pintles 29., 29. which are located in the U shaped bearings 3!), 38 which are fitted into. upper and lower slots 3i, 3! in the inner sides of the window casing, as more clearly shown in Figures 3 and 4. One of the overturned'ends, as 28a, of one of the cross slats. 27' has an outwardly turned tongue 32. v

Thereis a shaft 33 which works through, a suitable bearing inthe casing 23, as shown in Figure 3, and whoseinner end has a sleeve ,34 welded thereon and provided with a transverse slot 35 to receive the tongue 32; This sleeve works through a bearing 35 in' the window casing and its outer end 'has a crank 37 thereon Within the casing 23. A link 38 has one end pivoted to the" free end of the crank 3'! and has its other end pivoted to a nut 39 which is threaded onto the outwardly threaded s'haft "t9 whose ends are mounted to rotate in bearings in the casing 23; The inner end of the shaft is is extendedinto a bore in-the inner side of the window casing i, and is polygonal in shape to receive the socket a sash therein; a transverse shaft rotatably mounted on the casing, lift levers pivoted at one end to the casing and pivoted at the other ends to the lower part of the sash, swinging elements pivoted at their upper ends relative to the casing, links connecting the lower ends of said elements to the sash, means connecting said levers and elements with the shaft, said levers being mounted'toelevate the sash and swinging elements being mounted to the upper end of the sash to move it from the casing when the shaft is rotated in one direction and said levers and elements being mounted to lower the sash and moveit into sealing relation with the casing when wrench 42 by means of which it may be turned.

Upon turnin the wrench 42 in one direction the shaft 49- will be correspondingly turned and will actuate the 'nut 39, which in turn will cause rotation of shaft 33 so as to close the Venetian blind and when turned in the other direction the blind will be operated into open position.

The drawings and description are illustrative merely while the broad principle of the invention will be defined by the appended claims.
